Stainless steel round bars 1.4301 / 304

What this product is

Stainless steel round bars 1.4301 / 304 are solid cylindrical rods made from austenitic chromium‑nickel stainless steel commonly identified as 304 in the AISI/ASTM system and as 1.4301 in the EN/DIN system (also shown as X5CrNi18‑10). This grade contains relatively low carbon and typically about 18% chromium and 8–10% nickel, giving it the characteristic corrosion resistance and formability of 304 stainless.

Key material characteristics

304 / 1.4301 stainless steel provides:

• Corrosion resistance: effective in many atmospheric and mild chemical environments; suitable for food processing and indoor/outdoor architectural use. (For aggressive chloride or marine environments consider 316.)
• Austenitic structure: non‑magnetic in the annealed condition and retains good toughness down to low temperatures.
• Good weldability and formability: can be welded, bent and formed using standard techniques; commonly used for fabrication and welding projects.
• Moderate machinability: easier to machine than some other stainless grades with appropriate tooling and speeds.

Typical uses of stainless steel round bars 1.4301 / 304

Round bars in 1.4301 / 304 are versatile and used across many sectors. Common applications include:

• Food processing and catering equipment — shafts, pins, conveyors and components that contact food (stainless, easy to clean and sanitary).
• Architectural and finishing works — handrails, balustrades, decorative rods and supports.
• Automotive and general engineering — shafts, studs, fasteners and turned parts.
• Manufacturing and workshop projects — tooling, spindles, dowels and custom fabricated parts for both hobbyists and professional fabricators.
• Light chemical and pharmaceutical equipment where corrosion resistance and cleanability are required.

Who buys these round bars

Customers range from DIY and garage machinists to industrial fabricators, architects, building contractors and maintenance teams. Because the product is easy to weld and form, it is popular with metalworkers and engineers making bespoke components as well as buyers sourcing standard stock materials for production runs.

Standards and naming

This category uses the following common names and standards: 1.4301 (EN/DIN), 304 (AISI/ASTM), and sometimes listed as X5CrNi18‑10. In the UK and EU these EN/DIN designations are widely used alongside the AISI 304 label familiar to international buyers.

Practical selection advice

Choose 1.4301 / 304 round bars when you need a general‑purpose, corrosion‑resistant material with good formability and weldability. If your application involves prolonged exposure to chlorides (seawater, de‑icing salts) or highly aggressive chemicals, consider specifying a more highly alloyed grade such as 316. For heavy duty high‑temperature or highly acidic service, consult our product range or technical team for a more suitable heat‑resistant or acid‑resistant alloy.

Quality and supply

All round bars in this category are supplied as stainless steel products; our shop specialises only in stainless, acid‑resistant and heat‑resistant steels. If you need material certificates, cut‑to‑length service, or machining, please check the product options or contact our sales team for assistance.

Summary

Stainless steel round bars 1.4301 / 304 are a reliable, widely used choice for components that require corrosion resistance, weldability and good formability. They serve a broad range of industries from food processing and construction to automotive and general engineering — a cost‑effective, versatile option for both professionals and hobbyists.
